Why it's interesting
Joules defines its brand as encompassing the values of "time-off, heritage, countryside, Britishness, family and fun", which is clearly striking a chord with UK and international consumers.
The group has said its trading to date in the current financial year has been in line with expectations and early feedback on its spring and summer 2017 ranges has been positive.
What Joules said
Chief executive Colin Porter said:
The 2016 financial year was a transformational year in the development and expansion of the Joules brand which included our successful admission to AIM in May.
We have delivered strong growth across our retail and wholesale channels, significantly increasing profitability by effectively leveraging our operating cost base. Our active customer base and international sales have also grown impressively, all of which is great testament to the growing strength and appeal of Joules as a premium lifestyle brand.
